Title:
体積または質量流量を測定するための装置
Document Type and Number:
Japanese Patent JP4653102
Kind Code:
B2
Abstract:
The present invention provides apparatus for measuring volumetric or mass flow of fluid. The apparatus comprises a capsule that is adapted to move upwardly and downwardly within a housing and receive fluid from a tube. The apparatus further comprises force exerting means and preferably a magnetic means that is adapted to exert force on the capsule, the force is proportional to a position of the capsule within the housing. The force is measurable and controllable. A seal is provided in the capsule's bottom opening so as to fluidically block the capsule and a pin is provided so as to push aside the seal when the capsule is downwardly positioned and is filed with fluid so as to drain it. The number of times the capsule is drained in a predetermined time can be calculated so as to attain the volumetric flow rate of the fluid through the apparatus.
